DETAILED DESCRIPTION OF THE INVENTION

(S)—N—((S)-1-cyclohexyl-2-{(S)-2-[4-(4-fluoro-benzoyl)-thiazol-2-yl]-pyrrolidin-1-yl}-2-oxo-ethyl)-2-methylamino-propionamide(structure depicted in Formula (I)) and its hydrate(s) exist indifferent forms. The disclosure provides, at least in part, the H_(A),A, B, C, and D crystalline forms for the compound of Formula (I).

The crystalline forms of compound of Formula (I), its salts and solvatescan be characterized by a number of methods, including but not limitedto, Powder X-Ray diffraction (PXRD), simulated powder X-ray patterns(Yin. S.; Scaringe, R. P.; DiMarco, J.; Galella, M. and Gougoutas, J.Z., American Pharmaceutical Review, 2003, 6, 2, 80), Differentialscanning calorimetry (DSC) experiments, Solid-state C-13 NMRmeasurements, (W. L. Earl and D. L. VanderHart, J. Magn. Reson., 1982,48, 35-54), Raman spectroscopy, Infra-red spectroscopy, Moisturesorption isotherms (VTI—variable temperature isotherms), and hot stagetechniques.

The forms may be characterized and distinguished using single crystalx-ray diffraction, which is based on unit cell measurements of a singlecrystal of a particular form at a fixed analytical temperature. Adetailed description of unit cells is provided in Stout & Jensen, X-RayStructure Determination: A Practical Guide, Macmillan Co., New York(1968), Chapter 3, which is herein incorporated by reference.Alternatively, the unique arrangement of atoms in spatial relationwithin the crystalline lattice may be characterized according to theobserved fractional atomic coordinates. Another means of characterizingthe crystalline structure is by powder x-ray diffraction analysis inwhich the diffraction profile is compared to a simulated profilerepresenting pure powder material, both run at the same analyticaltemperature, and measurements for the subject form characterized as aseries of 2θ values.

One of ordinary skill in the art will appreciate that an X-raydiffraction pattern may be obtained with a measurement error that isdependent upon the measurement conditions employed. In particular, it isgenerally known that intensities in a X-ray diffraction pattern mayfluctuate depending upon measurement conditions employed. It should befurther understood that relative intensities may also vary dependingupon experimental conditions and, accordingly, the exact order ofintensity should not be taken into account. Additionally, a measurementerror of diffraction angle for a conventional X-ray diffraction patternis typically about 5% or less, and such degree of measurement errorshould be taken into account as pertaining to the aforementioneddiffraction angles. Consequently, it is to be understood that thecrystal forms of the instant invention are not limited to the crystalforms that provide X-ray diffraction patterns completely identical tothe X-ray diffraction patterns depicted in the accompanying Figuresdisclosed herein. Any crystal forms that provide X-ray diffractionpatterns substantially identical to those disclosed in the accompanyingFigures fall within the scope of the present invention. The ability toascertain substantial identities of X-ray diffraction patterns is withinthe purview of one of ordinary skill in the art.

Likewise, it is to be understood that any crystal forms that providedifferential scanning calorimetry (DSC), thermogravimetric analysis(TGA), and/or moisture sorption isotherms patterns substantiallyidentical to those disclosed in the accompanying Figures fall within thescope of the present invention. The ability to ascertain substantialidentities of these patterns is within the purview of one of ordinaryskill in the art.

It is challenging todevelop an oral formulation, especially at high dosage strength, i.e.,the weight of the drug substance(S)—N—((S)-1-cyclohexyl-2-{(S)-2-[4-(4-fluoro-benzoyl)-thiazol-2-yl]-pyrrolidin-1-yl}-2-oxo-ethyl)-2-methylamino-propionamide(compound of Formula (I)) exceeds 100 mg. Typically, the amount of drugsubstance at high dosage strength is about 100 mg, 125 mg, 200 mg, 250mg, 300 mg, 400 mg, 500 mg, or 600 mg.

The amount of(S)—N—((S)-1-cyclohexyl-2-{(S)-2-[4-(4-fluoro-benzoyl)-thiazol-2-yl]-pyrrolidin-1-yl}-2-oxo-ethyl)-2-methylamino-propionamide,its salt(s), and solvates (including hydrates) ranges from 5-600 mg ineach oral dosage form. In one embodiment, it is from 10-100 mg. Inanother embodiment, it is from 100 to 600 mg. In yet another embodiment,it is from 200-600 mg. In still another embodiment, it is from 250-500mg. Specifically, the amount could be 10, 20, 50, 100, 125, 150, 200,250, 300, 400, 500 and 600 mg.

The manufacturing process for low dose including 10 mg and up to 50 mgconsists of weighing of excipients and drug substance. This is followedby blending of drug substance with excipients like Microcrystallinecellulose, Mannitol, Dicalcium Phosphate, Spray dried Lactose, Polyvinylpyrollidone XL, Starch, Colloidal silicone dioxide and magnesiumstearate; preferably with Dicalcium phosphate, Microcrystallinecellulose, Polyvinyl pyrollidone XL and Colloidal silicone dioxide toobtain a pre-blend. The pre-blended is lubricated with magnesiumstearate, and compressed to obtain cores which are film coated. The drugload varied from 7% up to 36%. But preferred from approximately 10% toapproximately 18%.

The manufacturing process for the tablets containing more drugsubstance, including 250 mg and higher, preferable 300 mg or higher, 400mg or higher, 500 mg or higher, starts with weighing of the excipientsand drug substance. Once all excipients and drug substance are weighed,the drug substance is dry blended with microcrystalline cellulose,especially Avicel PH101 in a high shear mixer. The blended material iswetted preferably with PVP-K30 in a water solution. The wet mass iskneaded to obtain a granulate. The granulate is dried preferably is afluidized bed dryer followed by screening. The screen granulate islubricated to obtain a final blend which is compressed to obtained coresthat are film coated.

High ejection forces are observed with formulations containing Mannitol.

This problem is resolved by replacing Mannitol with Dicalcium phosphateor Lactose and decreasing the drug load. In some instances sticking andhigh variation in compression force are observed, normally, associatedwith Inadequate lubrication and bad flow. This is resolved by decreasingthe drug load.

Based on the experience from 10 and 50 mg formulation development,several compaction simulation trials on a single punch machine arecarried out in an attempt to develop higher strength (e.g. 250 mg) bysimulating roller compaction process. Several trials are done, to assessthe processability, using combination of excipients likemicrocrystalline cellulose, pregelatinized starch, dicalcium phosphateand mannitol as fillers and hydroxypropyl cellulose, Kollidon VA64, asbinders. Several issues like bad flow, sticking poor compaction areobserved even at drug load of about 30%. These problems could not besolved by qualitative or quantitative variations of the excipients. Itis thought that milled drug substance, with greater surface area (hencegreater bonding area) would provide stronger compacts/granulate provinggranules on milling that can be processed; however no significantimprovement is seen. These compaction simulation results are unexpected.No attempt was made to reduce the drug load below 30% as that would haveincreased the size of tablet considerably; inconvenient for the subjectespecially when intake of multiple tablets is planned in the clinicalstudy.

The technical manufacturing problems are successfully solved and higherdrug load (greater than 40% w/w, greater than 50% w/w, greater than 60%w/w, greater than 70% w/w, or greater than 80% w/w) is obtained by usingthe wet granulation and/or the dry granulation processes. In a wetgranulation method, the high dosage strength with a high drug load(e.g., 50% w/w) is possible with specifically selected and adjustedconventional excipients and granulating solvent
